The Pro 300 Series tripods are solid, full-size, ruggedly built and ready for any adventure. Whether it's a quick trip to the park or the scorching heat of Death Valley, the Pro 300 Series offers rock-solid performance and is ready to go at a moment's notice. At the heart of the new series is a completely redesigned, low-profile tripod neck and a new Rapid Flip Mechanism (RFM) that makes it easy to adjust leg angles. With a simple "flip," you can now adjust the leg angles to increase stability on uneven surfaces and reduce the overall height of the tripod for creative perspectives from low angles. There is also an accessory port on the side of the tripod neck that accepts ¼ 20" or 3/8" accessories such as magic arms for holding lights, phones or tablets.
